FIG. 1 is a perspective view showing front, left and bottom features of a first embodiment of our design;

FIG. 2 is a perspective view showing front, right and top features thereof;

FIG. 3 is a front elevational view thereof;

FIG. 4 is a left side elevational view thereof;

FIG. 5 is a right side elevational view thereof;

FIG. 6 is a bottom plan view thereof;

FIG. 7 is a top plan view thereof;

FIG. 8 is a perspective view showing front, left and bottom features of a second embodiment of our design;

FIG. 9 is a front elevational view thereof;

FIG. 10 is a perspective view showing front, left and bottom features of a third embodiment of our design; and,

FIG. 11 is a front elevational view thereof.

Left, right, bottom and top views of the second and third embodiments are not shown inasmuch as they are identical to and would merely repeat what is already depicted in the left, right bottom and top views of FIGS. 4, 5, 6 and 7, respectively. 

We claim the ornamental design for front portions of a rotatable operating knob with escutcheon plate for latches and locks, as shown and described.
